The comfort of vehicle occupant-seat system, an important factor in vehicle comfort, will be taken as research object. Based on human musculoskeletal model, the uniform modeling of human biodynamics will be researched to obtain human body interface pressure distribution, human response to vibration and human lumbar spine load etc. This model would provide new approach to understand occupant-seat comfort from the view of human biodynamics. With the fusion of human subjective evaluation, body pressure distribution, human response to vibration and human lumbar spine load, the co-model of human subjective and objective evaluation will be established with optimized support vector machine. It will be a guide for evaluating seat comfort scientifically. Then the influence of seat structure parameters on occupant-seat comfort are investigated, such as physical characteristics of seat cushion, local support and other seat design parameters. Furthermore, taken human biodynamic parameters as optimization objective, the structure optimization method of seat foam will be researched, especially on modeling and solving. Finally, the vehicle seat was used to verify and improve the above models and methods. Throughout the study focused on occupant-seat comfort with human biodynamics and ergonomics, the results would provide new method for mechanism of occupant-seat comfort and development of seat. This project could enhance the research of occupant seat system comfort.
